Technical Analysis
AWS CDK's asset bundling process, when invoked with a Docker file, could be manipulated to insert symlinked files or directories into the output bundle that were not explicitly provided as input. This improper link resolution vulnerability affects aws-cdk-lib versions before 2.267.0, allowing Docker files to introduce symlinks into the bundled assets unexpectedly.
Potential Impact
The vulnerability allows Docker files used in the asset bundling process to insert symlinked files or directories into the output bundle without those symlinks being part of the original input. This could lead to unexpected or unauthorized files being included in the deployed infrastructure assets, potentially impacting deployment integrity or security.
Mitigation Recommendations
A fix is available in aws-cdk-lib version 2.267.0 and later. Users should upgrade to version 2.267.0 or newer to remediate this issue. No additional mitigation steps are indicated in the advisory.
